ASSERTING AND ESTABLISHING PROVENANCE OF MEDIA CONTENT DURING LIVE STREAMING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18211159 titled 'ASSERTING AND ESTABLISHING PROVENANCE OF MEDIA CONTENT DURING LIVE STREAMING

The abstract describes a lightweight mechanism for asserting provenance during live streaming of media content and establishing provenance upon playback. This involves generating key pairs, signing manifest metadata and media content portions, and validating the provenance claims.

• Provenance claim generator creates key pair for live streaming, signs manifest metadata, and media content portions.
• Provenance claim validator verifies manifest metadata and media content portions during live streaming.
• Use of long-term private and public keys associated with the sender for signing and verification.
• Lightweight mechanism for ensuring authenticity and integrity of live streaming media content.
• Efficient way to establish provenance and prevent tampering during live streaming.

Potential Applications: This technology can be applied in live streaming platforms, online media content distribution, digital rights management systems, and secure communication channels.

Problems Solved: Addresses the need for reliable provenance assertion in live streaming environments, prevents unauthorized modifications to media content, and enhances trust in the authenticity of streamed content.

Benefits: Enhanced security and trust in live streaming media content, improved integrity of digital media distribution, and increased confidence in the origin of streamed content.

Commercial Applications: This technology can be utilized by streaming platforms, content providers, digital media distributors, and communication service providers to enhance security and trust in their offerings.

Questions about the technology: 1. How does the use of key pairs enhance the security of live streaming media content? 2. What are the potential implications of this technology for digital rights management systems?

Frequently Updated Research: Stay updated on advancements in digital media provenance technologies, security protocols for live streaming platforms, and innovations in secure communication channels.

Original Abstract Submitted

Lightweight mechanisms provide a way to assert provenance when live streaming media content and establish provenance upon playback. For example, a provenance claim generator generates a key pair including a live-stream private key and live-stream public key. The claim generator signs, with a long-term private key reliably associated with a sender, manifest metadata including the live-stream public key, thereby producing a manifest signature. During live streaming, the claim generator signs respective portions of media content with the live-stream private key, producing portion signatures for the respective portions. A provenance claim validator receives the manifest signature and manifest metadata. The claim validator verifies the manifest metadata using a long-term public key (reliably associated with the sender) and the manifest signature. During live streaming, the claim validator verifies the respective portions of the media content using the live-stream public key and the portion signatures for the respective portions.
